Patented Feb. 17, 1948 z ,iruiozfiv This invention relates lto a separator for removing, a liquid of one 'density from a liquid of another density, such as creamfrom milk within a' conventional type of container or bottle, and

has for the primary object the provision of a device operating on the self-starting s iphon princ'iple whereby cream may be drawn off ofmilk without unduly disturbingthe latter and which will be self-sustainingin -an operating position cna milk bottle and may be conveniently' adjusted 'in accordance with-the Vamount of cream to be removed from the milk which will permit the device to be used in conjunction with bottles o f different sizes containing milk and cream.

With these and other objects in view as will become more apparent as the description proceeds, Athe invention consists in certain novel features' of construction, combination and .arrangement -of parts as'will'be hereinafter more fully; described and claimed. Y

For .a complete understanding of my` inventlongreference is to be'had' to the following descriptio'n and 'accorxii'az'a.nyingdrawingss in which Figure 1 is a side elevation illustrating a separator constructed in accordance with my invention and showing the separator associated with a milk bottle.

Figure 2 is an edge elevation illustrating the separator.

Figure 3 is a sectional View taken on vthe line 3-3 of Figure 1.

Figure 4 is a fragmentary vertical sectional view illustrating the telescopic construction of the separator.

Referring in detail to the drawings, the numeral 5 indicates in entirety a separator consisting oi a tube which is of substantially U-'shape providing an arcuately curved connecting portion 6 and leg portions 1 and 8. The leg portion 8 is of a greater length than the leg portion 1 and the latter has its free end portion laterally offset, as shown in Figure 1, so`that when the separator 5 is arranged in a bottle, as shown in Figure 1, the free end of the leg portion 1 will be spaced a considerable distance away from the exterior wall of the bottle (shown in dotted lines) to permit a container (not shown) to be conveniently arranged thereunder for catching the cream as it ows from the leg portion 1.

Formed on the leg portion 1 and a part of the connecting portion 6 is a supporting member 9 in the form of a block, the thickness of which is substantially equal to the external diameter of v the tube and is provided with an arcuately curved seat I0 to engage with the bead of the neck 2 Claims. (Cl. 137-20) of the milk bottle as shown in Figure i for supporting the separator on the bottle with the leg` portion 8 extending downwardly in the milk bottle and substantially centrallythereoifwhile the.

i leg portion 1 is arranged exteriorly of the bottle and spaced throughout its length from the `ex terior wall ofthe bottle.

The 4leg portion 8 of the separator consists .Y of telescopic sections A and B. The section B has a sliding kiit withk the section A and is arranged exteriorly of the latter-named section and is provided with a port l I while the section A is provided with an elongated slot I2. The port Il communicates with the slot I 2. The slot andJ port will permit of the section B being adjusted endwise of the section A with the port Il Vremaining in communication with the interior of the section A by way of the slot I2. This vwill permit the port Il to be conveniently adjusted to the lowest level of the cream or where the latter meets with the milk, as indicated by thelv dotted lines C in Figure 1. I

The section B has its free end closed by a removable plug I3. The plug being removable will allow the tube of the separator to be conveniently cleansed by running a solution entirely through the tube from end to end thereof and, if desired, a suitable wire or other cleaning element may also be obviously passed entirely through the tube of the separator.

From the foregoing description taken in connection with the accompanying drawings, it will be seen that a separator operating on the siphon principle has been provided which when applied to a bottle will position one leg portion of the separator centrally of the bottle and within the latter, while the other leg portion will be supported eXteriorly of the bottle and spaced from the walls of the bottle. Further, it will be seen that the port Il which takes in the cream from the milk bottle can be adjusted upwardly and downwardly in accordance with the amount of cream inthe bottle still remaining in communication with the section A of the tube. This arrangement will permit the separator to be successfully employed in connection with bottles of diierent sizes containing diierent amounts of cream and milk.

The operation of the separator device of the present invention starts automatically and immediately as the device is immersed in the liquid contents of the bottle or'container substantially the same as in conventional siphon devices formed and operating on the same general principle.

Further it is to be noted that (see Figure 1) the supporting member 9 is provided with an inconsequently locate the port il at a proper posiftion of taking olf the crean from the milk.

While this device has been specically described for the purpose of separating cream from milk, it

also may be employed for separating other liquids ,Y wherein the density of the liquids'within a contalner are different from one another.

While I have shown Iand described the preferijed embodiment of my invention, it will/be understood that minor changes 'in construction, combination and arrangement of parts may be made without departing from thespirit and scope ofthe invention as claimed.

Having vthus described my invention, vwhat I claim is:

1. In a separator of the character described, a tube of substantially U-'shape providing a pair Aof spaced apart leg portions, Vone to enterand the other'to be disposed outside 4of va container and a connecting portion joining said Aleg portions, a supporting member formed on the connecting portion :and adjacent pari; of the outer leg portion and comprising a block having a width thickness substantially equalto the external diameter `of the attached tube rportion and provided with an inclined bottom and an arcuately curved lateral seat to engage an outer annularbead of the neck of a milk bottle or like container for positioning said outer leg .portion exteriorly `of and spaced from the container with the other leg portion extending downwardly in the container .and centrally thereof, said latter-named leg portion including telescopic tubular sections with the inner section provided with an elongated longitudinal slot and the outer section provided with a restricted port communicating with said slot, whereby, upon relative longitudinal adjustment of said telescopic tube sections, the length of the inner leg of the device is varied and the relative position of the restricted opening is changeable for the removal of different quantities of liquid from the container to which y,the device is applied.

2. In a separator of the character described, a

i tube of substantially U-shape providing a pair of spaced-apart leg portions, one to enter and the 4other to be disposed outside of a container and sa ,connecting portion joining said leg portions, said leg portion for entering the container includ- Ying telescopic tubularsections, one of which is movable longitudinally of the other, with the other section. provided with an elongated longitudinal slot, and the one section provided with a restricted portcommunicatlng'with said slot, whereby'J vupon relative longitudinal movement of said sections,

the length of the inner legof the device `is varied and the relative'position of the port is changedA for the removal ,of different vquantities of liquid from the container to whichsaid device is applied- S. WRISLEY.
